The show was a very intelligent yet slow paced adaptation of very high quality source material. Sometimes I got impatient in certain episodes, but am glad that I stayed the course. Benedict cumberbatch was OUTSTANDING in the role. Just brilliant. His expressions, that quiver of emotion...it said much more than words. There were some deep moments, very poignant as well. Some witty ones also. I would have rated it 7.5 if option was there. Just stay with this show, it will be a rewarding experience.
